Wait for files on Google Cloud Storage.
This trigger will poll every interval a GCS bucket. You can search for all files in a bucket or directory in from or you can filter the files with a regExp.The detection is atomic, internally we do a list and interact only with files listed.
Once a file is detected, we download the file on internal storage and processed with declared action in order to move or delete the files from the bucket (to avoid double detection on new poll).

Wait for a list of files on a GCS bucket and iterate through the files. Delete files manually after processing to prevent infinite triggering.

MOVEDELETENONEThe action to perform on the retrieved files. If using 'NONE' make sure to handle the files inside your flow to avoid infinite triggering.
The directory to list
The GCP service account to impersonate.
60durationInterval between polling.
The interval between 2 different polls of schedule, this can avoid to overload the remote system with too many calls. For most of the triggers that depend on external systems, a minimal interval must be at least PT30S. See ISO_8601 Durations for more information of available interval values.
DIRECTORYRECURSIVEDIRECTORYThe listing type you want (like directory or recursive)
if DIRECTORY, will only list objects in the specified directory
if RECURSIVE, will list objects in the specified directory recursively
Default value is DIRECTORY
When using RECURSIVE value, be careful to move your files to a location not in the from scope
The destination directory for MOVE action.
The GCP project ID.
A regexp to filter on full path
ex:
regExp: .* to match all files
regExp: .*2020-01-0.\\.csv to match files between 01 and 09 of january ending with .csv
["https://www.googleapis.com/auth/cloud-platform"]The GCP scopes to be used.
The GCP service account.
